To all whom it may concern:

Be it known that I, DORUS GRIFFITH'FREE- out in the claims.

One ofthe principal objects of the invention is to provide a device of this kind of an embodiment to overcome numerous disadvantages and objections encountered in the use of many other contrivances hitherto devised for similarpurposes.

A further object is to provide a device of the character specified which may be set or adjusted to automatically engage and lock the Window-sash to prevent either the lowering'of the same after being raised or the raising the position originally occupied'thereby.

A further object is to provide a device of this character which may be set or adjusted to automatically engage and lock the windowsash to prevent either the lowering of the same after being raised or the raising thereof afterbeing'lowered, while still permitting it to be further raised or lowered from any intermediate position to which it may have'been carried or moved in the first instance.

' A still further object ofthe invention is to provide a device for the purposes specified which is simple in construction and comparatively inexpensive to manufacture, besides being thoroughly effective and reliable in operation and possessing the capacity for long and repeated service, v

The above and additional objects. are attained by means substantially such as are illustrated in the accompanying drawings, formingv a part of this specification, in which similar characters of reference indicate corresponding parts'in all the news.

Figure 1 is a side elevation, in part section,

on the line 11 of Fig. 2, illustrating portions of a window frame and sash having myimprovements embodied in connection there- 2. Fig. 4 is a similar view to Fig. 1, the position of the parts being reversed and the section being on the line 4 4 of Fig. 2, the position of the locking-bolt in this figure being such as to catch and lock the window-sash against movement in an upward direction; and Fig. 5 is a detail view of a portion of the member employed on the window-sash for on abling the locking-engagement of the bolt to be effected.

Before proceeding with a more detailed description it may be stated that in the form of my improvements?- herein shown I employ a specially constructed supporting frame or case for the operative members or elements of the device, which is suitably secured within a mortise or recess therefor formed in the in-' her face of one of the side members of an or-. dinary window-frame. Mounted. within said frame or case is a specially-constructed doubleacting bolt, combined with which are specially constructed members cooperating with each other and with the bolt for maintaining the latter normally in a neutral position and permit-. ting the window-sash to be freely raised or low' ered to any desired height or position. Said members are also of special organization and are capable of being operated to cause the bolt to be carried or swung to either one of two positions, so as to catch and lock the window-sash either when raised or when closed to prevent movement thereof in the opposite or reverse direction until a proper release of the bolt has been effected. Special means are employed on the adjacent face of the windowsash by'which to secure the desired locking engagement of the bolt with the sash, and while I have, herein represented myimprovements in a certain preferred embodiment it: will be understood, of course, that I am not limited thereto in precise detail, since imma-. teria'l changes therein may be resorted to coming within the scope of my invention. 4 1

Reference being had to the drawings by the designating characters thereon, 1 represents a portion of one of the upright members of an ordinary window-frame, having formed in the inner face thereof at the proper height a mor tise 2, in whichisseated or located a suitable supportingframe or case for the movable or operative members of the structure, said frame comprising a back section 3, lying flatly against the base of the said mortise 2, togethenwith parallel side sections 4 and 5, eachof which is'formed at the forward or outer edge thereof with an. integral substantially.

right-angled flange 6, which is secured to the face of the upright member 1 on either side of the vertical edges of the saidmortise 2 therein by means of screws 7 or in any other suitable way, these flanges being partially covered by the vertical parallel guides 8 for the window-sash 9, and which guides incidentally add to the security of the fastening for the said supporting frame or case within the mortise, it being understood that the parallel side sections 4 and 5 of the supporting frame or case closely fit against the adjacent sides of the said mortise 2. The said side sections 1 and 5 of the supporting frame or case are formed with corresponding openings 10 and 11, the former of which coincides or registers with a socket 12, leading from the forward side of the mortise 2, and the latter of which registers or coincides with an opening 13, leading from the opposite side of the said mortise 2 and terminating outwardly, preferably at the base 1 1 of a recess 15, formed in the outer face of the said member 1 of the window-frame. Working in the coinciding or registering openings referred to and having the inner end thereof received in the socket 12 is a rotatable shaft 16, having a flattened portion 17 at a suitable part of the length thereof and provided at its outer end with an operating-button 18, preferably of oval form, so as to serve as an indicator for denoting the position which the concealed members of the structure may occupy at any time. Mounted upon the said shaft 16 and rotatable therewith is a cam 19, having in the under side thereof a transverse groove 20, between the sides of which are snugly received the sides of the said flattened portion 17 of the shaft, the forward or operative face of this cam being struck on a curve (indicated at 21) and having therein a circumferentially-disposed groove 22, the sides 28 and 24 of which are disposed Vertically, the upper extremity of the said side 2 1 extending somewhat higher than the corresponding extremity of the said side 23, (indicated at 243,) for the purpose presently to be explained. Also mounted upon the shaft 16, beyond the said cam 19, is a doubleacting bolt 25, having independent swinging movement relatively to the shaft, and the inner edges 26 and 27 of which converge toward and intersect with each other directly adjacent to theopening 28 therein, through which the shaft passes, this construction furnishing a convenient pivotal support for the said bolt or catch on the shaft, as will be apparent. At a convenient elevation with respect to the shaft and on the side thereof adjacent to the said cam 19 this double-acting swinging bolt or catch 25 is provided with duplicate parallel projections or abutments 29 and 30, between which is disposed theupper free extremity 31 of a spring-lever 32, the lower extremity of which is curved inwardly to form a how 33, which extends within or is received into the space formed between the adjacent side section 5 of the supporting frame or case referred to and a forwardly-extending projection 34:, struck up from the back section 3 of said frame or case, the terminal 35 of said bow 33 being introduced within an opening 36 in said side section 5 and bent in such manner as to retain the said spring-lever in its desired working relation with the aforesaid cam 19 and double-acting bolt 25. As thus constructed and disposed within the supporting frame or case the said spring-lever 32, in addition to its function as such, also tends, through the aforesaid upper free extremity 31 thereof, to press laterally against the lip formed at 2 1 by the aforesaid extended upper portion of the side 23 of the groove 22 in the aforesaid cam 19. By means of the said forwardly-extending projection 34 the said spring-lever'32 is also held properly within the intended position therefor, and the said upper free extremity 31 of this springlever also tends to prevent any binding between the adjacent sides of the cam 19 and the bolt 25, thus permitting the said bolt to freely operate in the manner intended when not held under restraint by said spring-lever.

The inner face of the side section 5 of the supporting frame or case for the structure is provided with a projection 37, (see Fig. 2,) which serves normally to retain the cam 19 in such position as that the said double-acting swinging bolt 25 will be held in a neutral or inoperative position to enable the windowsash 9 to be freely raised or lowered without any engagement or locking thereof taking place. To provide for the locking engagement of the sash by the bolt, either to prevent the sash from being raised or lowered, as will be presently explained, the adjacent edge or face of the sash is provided with a plate 38, formed with a series of equidistant verticallydisposed openings 39, in which either the upper or lower end of the bolt 25 is received, according to the particular position to which the bolt may be caused to be thrown or adjusted. The said projection 37 on the inner face of the side section 5 of the supporting frame or case also operates as an obstruction to the cam 19 for preventing the latter from being carried too far inwardly or backwardly from a position corresponding with the neutral or normal position of the bolt, and thus also indirectly serves to retain the shaft 16 in such position as will bring the sides of the operating-button 18 thereof in vertical planes; but it will be understood that by applying suflicient force to the shaft through the medium of said button the cam 19 may be carried inwardly or backwardly past the said projection, by which the lower operative end of the bolt 25 will be thrown outwardly to be engaged in the openings 39 of the plate 38 on the window-sash, whereby the latter will be prevented from being raised until the re- ,any one of the openings 39 in the aforesaid plate 38 on the adjacent face of the windowsash, this being what has been. termed the neutral position ofthesaid bolt. The upper [end portion of the bolt is constructed to be top heavy, so that normally the same will tend to pitch forwardly ,or outwardly in ,the direction-of said window-sash, it beingnoted, however, that the bolt is held'under restraint from such action by pressure of thefree up: per extremity 31 of the spring-lever32 against the inner projection or abutment 3O fromthe adjacent side of the bolt; At this time the cam 19 and the said spring-lever 32 will be in the position also indicated, and the windowsash may be raised to any desired extent with.- in the guides therefor, as will be apparent. To lock the sash in its raised position, it is simply necessary to turn theoperating-button 18 of the shaft 16 in; the left-hand direction, whereupon by virtue of the sides of the flattened portion 17 of the said shaft fitting between the sides of thegroove 20 in the under side of the cam 19 the latter willbe rotated forwardly in such manner as to carry the free upper extremity 31 of the spring 32 away from the projection or abutment 30 of the bolt, thereby causing the upper and heavier end portionof the boltto gravitate or tip forwa-rdly or outwardly inthe manner already suggested, so that the upper flattened portion 40 of the bolt will be received in one of the openings in the plate 38.. This operation ofthe bolt 25 is indicated in dotted lines in Fig.

1, and it is apparent that whenever it is desired to release the sash from engagement by the bolt it is simply necessary to restore the operating-button 1860f the shaft 16 to its first position, which action will cause the upper free extremity 31 of the spring-lever 32 to be moved inwardly or backwardly with the corresponding movement of the cam 19 and thus again be carried into contact With the afore-- said projection or abutment 30 on the bolt.

' After lowering the window-sash in order to lock the same in its lowered-position it is simply necessary to turn the operating-button 18 of the shaft 16 in the right-hand direction past a vertical position, whereupon the turning. force applied to the shaft will be communicated to the cam 19, and the latter will be forced past the projection 37 on the inner side of the side section 5 of the supporting frame or case,--the inward pressure then exerted by the aforesaid upper free extremity 31 of the spring-lever 32 against the said projection or abutment 30 of the boltcausing the upper end of. the; latter to be carried inwardlyor backwardly, which of course carries the lower end this position of theparts the window-sash'can-- not be raised until the operating-button 18 of the shaft 16 hasbeen again operated reversely and carriedto its first or original position. It

will be understood that each time the parts are operated by turning theshaft in one direction or theuother through the medium of the button 18 they are temporarily locked in the intended operative positions therefor by lever, all of w-hich,it is thought, will be fully understood without further detailed explanation. I I 7 My improveddevice is capable of being ap- 1 plied for use in connection with window frames and sashes as ordinarily constructed, and it will be seen that the same possesses many ad'- vantages as a security device for preventing raising or lowering of the, window-sash except cooperative action of the cam and the springwhen the devices are operated in a certain or predetermined manner. I It will be understood that-the'upper end portion of the bolt may be rendered top-heavy either by sufliciently increasing the amount of material thereof or bymounting the bolt-somewhat below a transverse plane passing centrally therethrough between its ends or in any other way but it has been'found that the projections, or abutments. 29 and 30 thereon sufficiently add to the Weight thereof for all prac- T be carried into operative relation with said engaging device, at will, embodying a rotatable shaft, a cam and a spring-lever, said cam having a circumferentially-disposed groove therein, and the spring-lever having an extremity thereof located within said groove.
